Abstract:
Through centuries, the man try to optimize jobs, and reduce the costs. In transportations system, the compact one is more desirable. In this research the sand pneumatic conveying system, used in Garri-4 power plant CFB (Circulating Fluidized Bed) boiler, a problem of high rate erosion studied. And the research aiming to find optimum and reliable solution for it. Experimental test done by using sand-blasting machine to simulate and to test the proposed solution, which is the change of sand composition by mixing it with percentage of sponge coke powder, as well as the economic analysis done to evaluate and find the optimum solution. The study concludes that the mixture of 20% of sponge coke powder to sand has less erosion rate and more economical.
